Retrieve the JSON data from the server's response

Question

Retrieve the JSON data from the server's response

{"identifier":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}

After alerting the response data, I discovered the code snippet shown above. Now, how can I retrieve the value of the identifier?

The controller is set up to return like this:

return Json(
    new {
        id = indicationBase.ID
    }
);

When I reach the success function in my ajax call, this is what I have:

success: function(data) {
    var id = data.id.toString();
}

However, when checking data.id, it returns as undefined.

Answer №1

When the data is in JSON format and not a string, you can access the id property like this:

alert(response.id);
or
alert(response['id']);

If the data is not in JSON format, you can parse it as follows:

var response = JSON.parse('{"id":"2231f87c-a62c-4c-8f5d-b76d11942301"}');
response.id ; //# => 2231f87c-a62c-4c-8f5d-b76d11942301

One way to access it is by using its property name:

var bar = {"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"};
alert(bar.id);

Alternatively, if you have a JSON string that needs to be converted into an object:

var baz = jQuery.parseJSON(data);
alert(baz.id);
